Objective To evaluate and compare C5 palsy and closure of the opened lamina after expansive open-door Laminoplasty (EOLP) with miniplate or suture/anchor fixation.Methods Between January 2011 and January 2013,a total of 142 patients with cervical myelopathy who were treated by EOLP were divided into hinge-side fixation group (fixed with suture/anchor,78 cases)and open-side fixation group (fixed with miniplate,64 cases).The Japanese Orthopaedic Association (JOA) score was used for neurological assessment and recovery rate (RR) counting.Opening angles,cervical curvature index (CCI),posterior shifting of spinal cord (PSSC) and severity of cord compression were recorded and compared.Results All patients in both group were followed up for more than 12 months.All incisions healed by first intention.C5 palsy occurred in 9 patients (9/78,11.5％) of hingeside fixation group,and 1 patients (1/64,1.6％) of open-side fixation group,showing significant difference (P=0.047).Opening angles and PSSC in hinge-side fixation group were greater than that in open-side fixation group.PSSC of 10 patients with C5 palsy were 3.97±1.19 mm,and greater than that of other patients without C5 palsy 2.57± 1.01 mm.There was no significant difference in CCI before (12.23％±3.70％,11.38％±4.29％) and 1 week (12.12％±3.77％,11.31％±4.35％) after operation.No significant difference was found in JOA scores (12.35±1.09,13.55±0.91),JOA improvement rate (64.24％±9.49％,61.78％±11.48％) and cord compression (0.74±0.71,0.75±0.67) at 12 months after operation.In 6 months postoperatively,27％ of patients in hinge-side fixation group,none in open-side fixation group were identified with 10％ decrease or more in opening angles of lamina.Conclusion EOLP with miniplate fixation has the same clinical outcome as fixed with suture/anchor,but will reduce the incidence of C5 palsy and prevent further closure of the opened lamina.

By organizing and studying on the original works of LI Wenrong， this paper aimed to explore his theories and methods for treating liver diseases. LI Wenrong believes that the liver is easily prone to physiological disturbances， difficult to pacify， and can be compared to a “chariot” that moves horizontally and vertically， acting as a “general” for both civil and military affairs. Pathologically， liver diseases tend to spread to other organs， resulting in ever-changing pathological changes， often affecting emotional health. In terms of therapeutic methods， LI Wenrong proposes ten methods including draining fire to calm the liver， nourishing water to moisten wood， clearing metal to calm the liver， calming gallbladder and harmonizing liver， subduing yang with shell-drug， treating liver diseases by supplementing spleen， soothing the liver with sweetness， astringing the liver with sourness， relieving the liver with spiciness， and draining the liver with excess-fire. These methods have great guidance and reference value for contemporary clinical practice in traditional Chinese medicine.
